BILLIARD-CUE CHALKER.

SPECIFICATION forming part of Letters Patent No. 617,231, dated January 3, 1899.

Application nea March 7.1898.

To (all 'whom t 'may concern:

Be it known that we, CLARK AV. DEVORE and DAVID DEvORE, citizens of the United States of America, residing at Monongahela City, in the county of Vashington and State of Pennsylvania, have invented certain new and useful Improvements in Billiard Cue Chalkers, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in cue-chalkers; and it has for its object to provide novel and effective means for applying the chalk to albilliard and pool cue tip.

The device comprises a cylinder within which the chalk is held near one end and is adapted to be depressed and revolved by the pressure of the cue against the same. The revolving motion of the chalk may be acco1nplished either by providing the cylinder with spirally-arranged grooves, in which the pins` carried by the chalk-receptacle are adapted to travel, so as to revolve the receptacle and chalk as the same is depressed in the cylinder by the pressure of the cue against the chalk. This rotary motion of the chalk may also be obtained by arranging a worm-screw within the cylinder, said screw carrying the chalk-receptacle on its upper end and the threads thereof engaging with the two pins which are provided for this purpose, so as to revolve the worm-screw as it is depressed. In either form of construction a counterbalance-spring is provided for the purpose of returning the chalk to its normal position.

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this specification, and wherein like letters of reference indicate similar parts throughout the several views, in which- Figure l is a top plan view of our improved cue-chalker, showing the cylinder provided Fig. 2 is a longitudinal sectional view of the same. Fig. 3 is a perspective view of the chalk-holder employed in this form of construction. Fig. et is a plan view of the bearing-plate for the chalk-holder. Fig. 5 is a horizontal sectional view of the same. Fig. 6 is a top plan View of a modified form of construction. Fig. 7 is a longitudinal Serial No. 672,838. (No model.)

sectional View of this form of construction. Fig. 8 is a transverse vertical sectional view, taken on theline X X of Fig. 6, with the wormscrew removed. Fig. 9 is and end view of the device.

To put our invention into practice, we provide a cylinder a, which may be secured toa suitable bed-plate b in any desired manner, the latter being provided with apertures c for fastening the same firmly to the -billliardtable or in any positionwhere lt is desired to locate the chalker. This cyli der a in the form of construction shown in igs. l and 2 is provided with spirally-arran ged grooves d, which are adapted to receive the pins e, carried in opposite sides of the cup f, which holds the chalk g. The recess of this cup is preferably square in its form, as shown at f', so that the block of chalk will be held rmly therein and prevented from rotating except in unison with the cup or holder. The rear end of the cylinder c may be closed by anvllordlinary screw-cap h, while the front end of the same is closed by a cap la, which is provided with a scoop-shaped mouth 7c', the extending portion of this scoop-shaped mouth forming a support for the cue near its tip and serving to hold the tip more evenly in engagement with the chalk. The cylinder when provided with the spirally-arranged groove CZ may be strengthened by means of the bar d, extending along the top of the same throughout its entire length, and which may be soldered or otherwise secured to the cylinder. This bar serves the same purpose on the top of thecylinder as the plate l) serves on the underneath side of the same.

The cap 7c is locked in position by means of pins Z, arranged near the end of the cylinder c, and which are adapted to enter the angle-slots Z', provided therefor in the rim of the said cap 7c. By this construction this front cap may be readily removed to place a new piece of chalk in position in the cylinder.

The cup fis provided on its underneath face witha centrally-arran ged pivot f2, which engages in the bearing-plate f3, this plate be* ing provided with flanges f4 and f5, the latter being arranged interior-ly of the former and thereby forming a circumferential groove f6, which receives the upper end of the spiral ret-racting-spring m, arranged within the cylinder between the aforesaid bearing-plate and the cap h.

In Figs. 6 and 7 we have shown a modified form of construction in which a worin-screw is provided to accomplish the rotating of the chalk when the pressure of the cue is brought to bear against the same in the same manner as is accomplished by the cupf and the spiral groove provided in the cylinder shown in Figs. l and 2. In this form of construction we employ the plate Z9, of the same form as heretofore described, and secure the cylinder a firmly thereto. rl`he same form of front cap 7c and scoop-shaped mouth tmaybe employed in this form of construction, and the cap may also be secured firmly in its position in the same manner as before described. In this form of construction we secure the rear end of the cylinder and cap 7i', which is formed integral with the sleeve h2, of less diameter than the cylinder and which receives the one en'd of the tube h3, closed at its lower end by an ordinary screw-cap h4. This tube h3 has arranged therein the retracting -spring h5, which supports the bearing-plate g', provided in its upper face with the concave recess g2, which receives the pointed end of the wormscrew g4. On the upper end of this wormscrew is secured the cup g5, which receives and holds the chalk. The rotary motion is communicated to the worm-screw as it is depressed by means of screws or pins 7a2, which are supported by the sleeve h2 and engaged within the spiral grooves of the worm-screw.

It will be observed that in either of these constructions the principle involved is the same, and when the tip of the cue is placed against the chalk and pressure brought to bear upon said cue the chalk will be forced inwardly within the cylinder d or a and will also be rot-ated during its said inward movep out departing from the general spirit of our invention.

Having fully described our invention, what We claim as new, and desire to secure by Letters Patent, is

1. In a device of the character described', the combination of a cylinder, a base-plate to which said cylinder is secured, a screw-cap engaging the forward end of said cylinder and provided with a scoop-shaped mouth, a screwcap engaging the rear end of said cylinder and having formed integral therewith asleeve lof less diameter than the cylinder, a chalkcup arranged within said cylinder, a wormscrew connected to the base of said chalk-cup the rear end thereof being pointed and extending into the sleeve, a tube engaging in said sleeve, a screw-cap engaging the rear end of said tube, a bearing-plate arranged within the tube and provided on its front face with a recess to receive the pointed end of the worm-screw, pins secured in the sleeve on two opposite sides and engaging the wormscrew to impart a rotary motion thereto when the screw is depressed within the tube, and a retracting-spring arranged in said tube between the bearing-plate and the screw-cap to return the screw to its normal position, substantially as shown and described.

2. A device of the character described comprising a cylinder, a chalk-cup mounted in said cylinder, a base-plate to which said cylinder is secured, a cap engaging the forward end of said cylinder and provided with a scoop-shaped mouth,having an extending portion, a screw-cap engaging the lower end of said cylinder and means whereby the chalk is normally retained against the forward end of the cylinder, and additional means whereby the chalk-cup is rotated when the chalk is pressed upon by the cue, substantially as described.

In testimony whereof we affix our signatures in the presence of two witnesses.
